CAT CAMS camshaft for BMW 3.8L 24v

Here are our camshafts from Cat Cams for BMW 3.8L 24v

Description :

The Cat Cams camshaft will allow you to considerably increase the performance of your vehicle.

When a vehicle must receive extensive mechanical preparation to obtain results worthy of the name and above all a significant range of progression, work on the camshafts becomes inevitable.

When preparing the Cat Cams camshaft, two modifications are observed: the valve lift and the opening angle.

Valve lift allows you to change the length and opening angle, which causes less or more air to enter the combustion chamber.

You should know that more air entering therefore modifies the air/fuel mixture in the cylinders, which increases power at high revs.

Also, the greater the opening angle of the valve, the more the air flow increases, which promotes the air/fuel mixture and therefore more power.

Therefore for use in competition, leisure, circuit and other, the revs will be sharper, the character of your engine will be more furious and thus you will benefit from a better range of use which will become a real asset.

Without broaching the subject of driving pleasure which will increase your sensations tenfold.

Please note modifications to be expected: mechanical tappet reference CC010 - pellets reference TS102 - internal valve springs reference PAC-I95009 - external valve springs reference PAC-E95009.

These camshafts can also be used in M88 (3.4L) and S38B36 (3.6L) engines. FOR COMPETITION REQUESTS ONLY. The following details should be checked: - The camshafts should turn smoothly in the cylinder head, ensuring free stroke by machining where necessary - The distance between the valve seal and the retainer at full lift should be d 'at least 0.6 mm - A minimum valve spring travel of 1.0 mm at full lift must be provided - distance between valve and piston 1.0 mm (pref. 1.5 mm). check 5-15° before TDC on the exhaust, and after TDC on the intake. These profiles require racing cam followers with a shim between the cam follower and the valve (shim under the follower). It is not possible to use these profiles on std cam followers with the shim between the follower and the cam (shim over follower). For use ONLY in competition engines with independent engine management (throttle position sensor) or carburettors.
